JOHN R. HUSSEY, OF INDIANAPOLIS, INDIANA.

SLIDING-DOOR CONSTRUCTION.

To all whom, it may concern:

Be'it known that I, JOHN R. HUSSEY, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Sliding-Door Construction; and I do hereby declare that the following is a full, clear, and exact description thereof, refer ence being had to the accompanying draw? ings, in which like numerals refer to like parts;

The object of this invention is to provide a new and improved means for mounting and transporting sliding doors on the ends of dryln'lns or in connection with any other building or structure It involves the method of handling two or more dry-kiln doors at either end of a kiln or battery-of kilns of even lengths.

It consists of a sliding-door track in front of and above said doors, which track-is in sections corresponding in length to the width of the jambs and doors alternately, which sections when in position form a single and continuous track. The sections fronting the j'jambs are immovably secured to the supports. The sections corresponding to the doors are in duplicate, called transfer and mainline sections, which are secured to a l movable transfer truss-beam parallel to the face of the building and the desired distance i from it, and said truss-beam is arranged to rest movably on its supports. It is provided wltha device for moving same in 1ts bearings.

These sections of track are arallel, of even lengths, are supported by .t e same means,

:and are the desired distance from each other :and from the face of the truss-beam. A door I is brought evenly on the transfer-section of and made to receive it.

the door is moved inagainst the building the main-line section of track takes exactly the position of the transfer-section of track occupied before removal and completes the connection in the mainline track broken by the inward movement of the transfer-track and remains in that position as long as the transfer-section is used in holding the-door in position. When ready to remove said door, the transfer truss-beam is thrown out to its original position, necessarily moving the tracks With it, when the transfer-track again be- Specification of Letters Patent.

comes a section of the general track and the substitute track becomes idle. One advantage of this arrangement is that the door is not supported from the door-cap immediately above the door-opening, but is supported by a truss mounted upon supports extending outward from the jambs between the openings, which supports may be strengthened by posts under their .outer ends resting on the floor. Hence the weight of-the floor will not affect the building or tend to sag the door-cap, as has been noticeable where doors are supported by the building immediately.

The full nature of the invention Will be understood from the accompanying drawings and the following descriptionand claims.

In the drawings, Figure 1 is a perspective view of the side of the structure with my said invention applied thereto, portions being broken away. Fig. 2 is a perspective view of a guide andsupport for the slide that carries each .end of said truss. Fig. 3 is a diagram of the front of the building having a plurality of openings therein and the track-sections and doors, the latter being shown in horizontal section on the line 3 3 of Fig. 4. Fig. 4 is .a vertical section through the truss-beamand upper part of the door, the truss-beam support being shown in side elevation, the door being here shown .closed. Fig. 5 is the same as Fig. 4 with the door open.

In detail, 10 represents a building or structure having door-openings .70 and jambs 71 between the openings. From it truss-beam supports 11 extend on a line aboveeachdooropening and beside each opening. The outer ends of said supports are reinforced and supported by posts 12 Upon each support 11 is placed a bearing-plate 1.3 with a longitudinal groove 14,

A transfer truss-beam is provided, consisting of the side pieces 16. (Shown in Figs. 5 and 6.) Said side pieces are secured at intervals by bolts 21 and 25 to castings or blocks 15 and 17, thus forming the truss-beam. The curved block has an extension 18, with a curved rib 19 on its under side to slide in the groove 14 of the bearing-plate 13.

The transfer-track section consists of two pairs of track-rails 22 .in the form of angleirons mounted beneath each truss upon L- shaped brackets 23, secured to :the plate 24, which is secured to the truss by the bolts 25. Thedoor 26 has near its upperend two brackets 27, carrying vertically-extending rods 28, on the upper end of which rollers 29 are IIO mounted. Said rollers are double-flanged rollers, each flange resting upon one of the oppositely-located track-rails 22, that constitute a pair, and the rod 28 extends down between the rails. The two pairs of tracks on the under side of the truss-beam are alike, so that the rollers of the door may run on either track.

The truss-beam is slidably moved outward away from the building on its supports by the hand-lever 30, fulcrumed to the plate 31, secured to the post 12. A rod 32 extends from said lever to a crank 33, secured to the crankrod 34, that is rotatably mounted in the bearings 35, secured upon the truss-supports 11. Another pair of cranks 36 are secured on said crank-shaft, and connecting-rods 37 are pivotally connected therewith and also to the eyes 38 on the casting 15, connected with the truss-beam. When the lever 30 is drawn downward, the truss will be removed outward, and when it is pushed upward the trussbeam will be moved inward. The bearingplate 13 has notches 39 in it for lubricating the bearing, so that the truss-beam will move easily. The transfer-track nearer the building may be called the "carrying-track and the outer one the substitute or mainline track.

There is a stationary track-section opposite and corresponding to the jambs 71, formed of a pair of tracks 40, supported on the under side of the timber-supports 11 by the bracket 41, as seen in Fig. 1. This track is always in line with the outer or main-line track under the truss-beam when the truss is pushed inward and with the inner transfer-track on the truss-beam when the truss-beam is pushed outward.

operation, assuming the door to be closed and supported on the transfer-track section, as shown in Fig. 4, the lever 30is drawn downward, so as move the truss-beam outward into the position shown in Fig. 5 and at the right hand of Fig. 3. Then the inner track on the truss-beam, which carries the door, will be in a line with the stationary track-sections on the jambs, and the door can be run off on the continuous track or main line, as will be seen clearly in Fig. 3. The door on the continuous track will pass all the closed doors, because the latter are on the transfer or carrying track sections and are in position close to the building. With this construction, therefore, the doors may be handled as desired, moved to any position, and past any closed doors. A door can readily be moved back from the continuous track to its particular transfer or carrying track section and then put into a closing position by moving the truss-beam inward, as shown in Fig. 4.

The door, it is seen, moves bodily outwardly from and inwardly into its seat formed by the Search rabbet 60 and surrounding the door on all four sides and which is as thick as the door.

I do not wish to be limited by the claims of this patent to the details of structure which I have shown herein, for the latter may be modified readily by any one without changing the nature of the invention.

What I claim as new, and desire to secure by Letters Patent, is I 1. The combination with a structure having a plurality of openings, and doors for closing said openings, a stationary track-section between eachpair of door-openings, a doubletrack section opposite each door, means for moving said double-track section so as to bring either track thereof into alinement with the stationary track-section, and means for supporting the door on the inner one of said double tracks in a closed position when the outer one of said double tracks is in alinement with said stationary track-section and so as to be movable longitudinally thereon when the inner one of said double tracks is in alinement with said stationary track-section.

2. The combination with a structure having a plurality of openings, of stationary track-sections between said openings, a trussbeam extending the full width of each opening and carrying two parallel track sections, said truss-beam being movable toward or away from said structure so as to bring either of said movable track-sections in line with the stationary track-sections, and doors for closing said openings, each door being movably mounted on the inner truss track-section and to be in a closing position when the outer track of the double-track section is in line with the stationary track-section.

3. The combination with a structure having a plurality of openings, of doors for closing said openings, a pair of supports secured to the structure one at each side of each opening, and in line with each other, a truss-beam mounted on each pair of side supports to be slidable toward and away from said structure, two parallel track-sections secured to each truss-beam, each being adapted to support movably the entire door, and stationary track-sections secured between the trussbeams with which either track-section on the truss-beams maybe moved into alinement, the arrangement being such that the door may be supported in a closed position by the inner one of said parallel track-sections when the outer one is in line with said stationary track-section.

In witness whereof I have hereunto afiixed my signaturein the presence of the witnesses herein named.
